Description

[Detailed explanation of the invention] This invention relates to a container for storing, transporting, and storing foods such as frozen foods and fresh foods, and its purpose is to make the container with a lid completely airtight. To ensure that frozen or refrigerated foods can be stored, and to store a large number of container bodies with open lids stacked, especially when refrigerating, by forming a predetermined gap between each container body, it is possible to store inside each container body in a stacked state. The main feature is that it enables the circulation of cooled air so that fresh foods can be stored in a frozen or refrigerated state.

In conventional containers of this kind, when sealing the container body by putting a lid on it, it was only done by fitting the protrusions and grooves formed on the bottom surface of the lid and the upper edge of the container body, so the sealing was incomplete and frozen food This is a problem when storing refrigerated items such as, and in addition, there is a risk that the lid may come off carelessly when handling it during transportation, etc. To prevent this, it is recommended to apply sealing tape such as rubber tape to the joint between the main body 1 and the lid 2. However, protrusions 1' and 2' were formed at the corners of the outer surface of the main body 1 and lid 2 for reinforcement, making it difficult to attach the tape securely. Ta.

Furthermore, when stacking a large number of container bodies containing fresh food for refrigerated storage, it is necessary to create gaps between each container body to allow cooling air to circulate within the container bodies, but conventional container structures As shown in FIG. 5, supporting legs 21 are formed at the four corners and lower edges of the long sides of the container body 1,
. . . The space between them was a gap 22 for air circulation.

However, when stacking, each supporting leg 21... is originally narrow, and by forming the protruding edge 24, the width becomes even narrower and is supported on the upper edge 23 of the container main body 1, which has a complicated shape. This not only makes the stacked state unstable, but also complicates the structure of the lower surface of each support leg 21.

The present invention has been devised to eliminate the above-mentioned drawbacks, and will be explained in detail below with reference to the attached drawings.The container of the present invention consists of a combination of a container body 1 and a lid 2 molded from synthetic resin. In order to increase strength, the four corners are bulged inward and outward to make them thicker than the other side walls, and the outer bulge 3 is formed by leaving the upper end and forming a stepped surface 4. The step surface 4 is made completely flush with the outer surface 5 of the main body.

Further, protrusions 6 having the same height as the four corners of the upper edge or the four corners and the center of the long piece are formed, and the concave edges 7 between the protrusions 6 are formed.
* indicates a gap for cooling air to flow when the container bodies 1 are stacked.

A groove 8 for fixing the lid is continuously formed on the upper edge, that is, each protrusion 6...concave edge 7..., and the groove 8 is connected to the inner protrusion 9 in the concave edge 7... portion. An outer wall 11 that is continuous with the outer dashed line 10 in the protruding portion 6 .
A protrusion groove 14 is formed by a groove bottom 12 continuous to the inner protrusion 9 and an inner wall 13' formed by extending the inner protrusion 13 upward.

On the other hand, as shown in FIGS. 1 and 2, the lid 2 is sometimes attached to the main body so that the outer surface 15 is flush with the outer surface 5 of the container main body 1, and the lid 2 is attached to the main body so that the outer surface 15 is flush with the outer surface 5 of the container main body 1. Recesses 16 that fit into the protrusions 6 of the main body 1 are formed at the corners and the center of the long sides, and the spaces between the recesses 16 fit into the concave edges 7 of the main body 1. The hanging edge 17... and the recessed portion 16...
A stopper edge 18 is formed on each of the hanging edges 17 to be fitted into the groove 8 of the container body 1.

That is, the retaining edge 18 has an inner protrusion 19 and an outer stepped surface 2 that are to be fitted into the protrusion groove 14 of the main body 1 in the recess 16 .
0, and the hanging edges 17... have an inner protrusion in order to engage with the inner protrusion 9 and the outer dashed line 10 of the concave edge 7 of the main body 1 in a latching state, contrary to the case in the recess 16. The outer step surface 20 is higher than the edge 19.

In the container of the present invention as described above, when the lid is closed, the outer surface 5 of the container body 1, the stepped surface 4 on the outside of the corner portion, and the outer surface of the lid 2 are flush with each other to form an airtight container. Therefore, there are no protrusions or irregularities on the outer surface of the joint between the main body 1 and the lid 2, and the sealing tape 25 such as rubber tape can be easily and reliably pasted, making the container even more securely sealed and allowing storage of cold items. Not only is this extremely convenient, but it also prevents the lid 2 from being accidentally opened or removed during transportation, storage, etc., and each step surface 4 is flush with the outer peripheral surface of the container body 1. none,
It is not just a simple casing without any protrusions on the outside, as is well known in the art, but as described above, this type of container has outer bulges 3 on the outer periphery of the four corners in order to increase the strength of the main body 1.・In the case where the structure is constructed by protruding, the upper end of each of the outer bulges 3 is intentionally made into a step surface 4,
This not only has the effect of making it easier to attach the sealing tape 25, but also has the effect of increasing the reinforcing effect of the container body 1 by the outer bulges 3 formed on the lower side of each step surface 4. be.

In addition, the groove 8 on the upper edge of the main body 1 and the retaining edge 18 of the lid 2 differ from the conventional structure in which the lid retaining structure is simply a groove and a protrusion that fit together, and in the case of the groove 8 of the main body 1, the inner protrusion 9, and the outer dashed line 10 is connected to the inner protrusion 9 at the four corner protrusions 6...
The outer dashed line 10 is made higher than the outer dashed line 10, and in the concave edge 7 between each protrusion, the inner raised edge 9 is made higher than the outer dashed line 10, and the stopper edge 18 of the lid 2 is configured accordingly. The inner projecting edge 19 and the outer step surface 20 are such that in the recesses 16 at the four corners, the inner projecting edge 19 is made higher than the outer step line 20, and the hanging edge 1
7... conversely, the outer step surface 20 is made higher than the inner protrusion 19, so the fitting structure between the main body 1 and the lid 2 when the lid is closed is such that the fitting structure is similar to that of the concave edge 7 of the main body 1. In this case, the outer step surface 20 of the lid 2 fits onto the inner side ridge 9 of the main body, and in the case of the projections 6 at the four corners, the inner side ridge 19 of the lid 2 is formed at the highest level of the outer step line 10. Therefore, when the lid is closed, M2 is partially fitted and closed to the main body 1 by fitting on the inside and fitting on the outside, so that the strength of the fitting is increased. , even if a load is applied to the lid 2 in the inward/outward direction, it will not shift, so the main body 1 lid 2
The projections 6 are formed on the upper edge of the main body 1, and when the main bodies 1 are stacked as shown in FIG. 4, the projections 6... Another main body 1 is mounted on top of the main body 1, and at this time, the concave edges 7 between the protrusions 6 act as gaps for air circulation, making it ideal for fresh foods, etc. stored in the main body 1. It can be maintained in a state of flowing air.

Furthermore, the stacking structure in which a protrusion 6 is formed and the bottom surface of another main body 1 is placed on top of the protrusion 6 makes the stacked state extremely stable compared to the case where containers of the conventional structure shown in FIG. 5 are stacked. There is no need to make any modifications to the lower edge of the bottom surface of the main body 1, and the structure is simple and convenient for manufacturing.
